DC Electrical Characteristics DC Chip-Level Specifications
Tabl e 14 lists the guaranteed maximum and minimum specifications for the voltage and temperature ranges: 4.75V to 5 .25V and -40°C
≤ TA ≤ 85°C, 3.0V to 3.6V and -40°C ≤ TA ≤ 85°C, or 2.4V to 3.0V and -40°C ≤ TA ≤ 85°C, respectively. Typical parameters apply to
5V, 3.3V, and 2.7V at 25°C and are for design guidance only.
